Application filed. September 25, 1905. Serial No. 279,917.

To all 'whom it may concern: Y

Be it known that I, JOSEPH H. CHAMP, a citizen of the United States,resident of Cleveland, county of Cuyahoga, and State of Ohio, haveinvented a new and useful Improvement in Pum s, of which the followingis a specification, the principle of the invention being hereinexplained and the best mode in which I have contemplated applying thatprinciple, so as to distinguish it from other inventions. i

The object of the invention is to rovide an improved pump,- particularlyadapted for application as a carbonating pump also par# ticularlyadapted for application as a lift pump.

The invention consists of the means hereinafter described, andparticularly pointed out in the claims. 4

In the drawings: The iirst five iig'ures illustrate the invention asapplied to a carbonating pump. The last two iigures illustrate certainmodification of the foregoing, in using the invention with a lift pump.The intermediate two igures illustrate an oiling device for the mainshaft.

Figure 1 is a front elevation.` Fig. 2 is a side elevation, with portionbroken away. Fig.k 3 is a top plan, with portion broken away,.and havinggear hood omitted Fig 4 is a detail, in to plan, on line 4 4 of Fig. 1.Fig. 5 is a detai partly vertical section and partly front elevation, ofplunger and valves and connecting passages. Fig. 6 is a detail, partlyvertical section and partly front elevation, of the journalY box havingthe oiling device. Fig. 7 is a vertical cross section on line 7 7 ofFig. 6. Fig. 8 is a detail, in front elevation, illustrating certainlmodiiication for using the invention with a lift pump, as distinguishedfrom use with a carbonating pump, as illustrated in the first iivefigures. Fig. 9 is a view, partly side elevation and partly verticalcross section, on line 9 9 of Fig. 8.

The horizontal main driving counter-shaft A has its two end portionsrunning in journal boxes a, respectively formed on the upper extremitiesof an upright bracket support B. Such bracket support isverticallyadjustable on the main su porting body C of the machine, bythe fol owing clamping mechanism:

Horizontal bolts b pass loosely through vertical slots b formed in theupperv and lower ortions of the two side members B of said racketsupport; and are screwthreaded in corresponding holes b2 formed in theface of the central upright portion' c of said main supporting body C.Said pair of journal boxes are formed on the u per ends of a pair ofhorns B2 constituting t e upper extremities of said bracket support B.The lower extremities of said side members B are respectively formedwith two laterally diverging arms B3,-each of the latter being providedwith a sleeve t3, in which is journaled the horizontal portion of thecorresponding plunger cylinder. The vertical adjustment of the bracketsupport B thereby carries the countershaft A, wlth its plunger equiment,

ltogether with the plunger cylinders aving suction and force equipment.

One extreme outer end of shaft A is provided w'ith gear wheel A', the oposite end of such shaft being provided wit disk A2. A wrist pin d,projecting outwardly from an eccentricfportion of gear wheel A, providesjournal bearing for the upper end of plunger D while a wrist pin d,projecting outwardly from an eccentric portion of disk A2, providesjournal bearing for the companion plunger D.

Plunger D works in vertical cylinder E. Plunger D" works in verticalcylinder E.

'The lower portion of cylinder E is formed with a horizontally extendingportion F' tol which reference has been made above as being journaled insleeve b3 of arm B3. The inner end of such horizontally extendingportion F is rotatably secured to a pipe G lat'- erally projecting fromvertical valve chamber H, by a suitablle fluid tigiptconrlieciopcomprlsing a ac ing rin a g an and stufling boli f2, Figs. Iand 5. Pipe G is formed with a passage that is thus adapted to aiordcommunication between the cylinder E and the central portion of thevalve chamber in question. The lower portion of cylinder E is formedwith al horizontal passage F extending towards, and connected by passageG with the central portion of, vertical valve chamber H. The lowerportions of such two valve chambers H and H are connected together byhorizontal inlet passage K; and their upper portions are connectedtogether by horizontal outlet passage L.

The connection of assage G with valve chamber H is centra y betweenconnection of inlet passage K and connection of outlet passage L, withsuch chamber II. The connection of passage G with valve chamber I-I iscentrally between connection of inlet passage K and connection of outletpassage L, with such chamber H. l

The plunger D, the plunger cylinder E, and passage connection of thelatter with valve chamber H, are respectively identical with plunger D,plunger cylinder E', and passage connection of the Ylatter with valvechamber H. One of such duplicate mechanisms is represented in Fig. 5,showing plunger D as operating in connection with valve chamber H andthe intermediate construction,as follows: Valve seat m is formed in theupper portion of the valve chamber, above the connection of such chamberwith its plunger cylinder. The portion of the valve chamber below suchplunger cylinder connection, is formed with a valve seat n. A valve M isadapted to seat downwardly upon said valve seat m. A valve N is adaptedto seat downwardly upon said valve seat a.

Gear wheel A meshes with pinion formed integral with spur wheel P, whici latter meshes with pinion s. Said spur wheel and pinion casting P p isjournaled loosely on a horizontal pin p; the latter projecting from therear portion of the outer face of the rearwardly extending arm a formedin same piece with the journal box a adjacent to gear wheel A. Pinion sis fast on pin s projecting outwardly from the end of the armature shaftof an electric motor S. Said gear wheel A being fast tothe counter-shaftA, and said pinion 8 being fast to the armature of the electric motor S;while the intermediate spur and pinion casting P p is loose onitsjournal pin p. The said motor is provided with bed lplate S, which issupported on upper horizontal rear extension c of the main supportingbody C of the machine. Clamping bolts s2 pass loosely through horizontalslots s3, rig t angular to counter-shaft A, formed in said bed plate S;and are threaded in suitable vertical holes 84 formed in said horizontalrear extension c.

From the foregoing description it will be obvious that thepump-mechanism proper may be readily adjusted to be operated by any ofthe various styles of motor adapted to the service here required. Thisis a matter oftentimes of considerable convenience inasmuch as where aspecial design of motor is needed for use in a machine of this kind suchmotor is not always readily available to the user and frequentlyobtainable by the manufacturer of the special machine only afterannoying delays and with general dissatisfaction as a result.

. An oil chamber e is formed centrally in each journal box a. A bronzebushing o is fitted in said box, respectively to opposite sides of suchoil chamber. A thin brass ring v2 rests loosely on shaft A, and has itslower portion depending below said shaft, within said oil chamber. A setscrew 113 passes through the wall of the journal box, opposite eachbronze bushing, and has pin end bearing against the correspondingluishing, to prevent the latter from turning.

Figs. S and 9 represent certain. modification, when the invention is tobe applied to a lift pump, as distinguished from a carbonating pump. lnsuch application, the supply coupling fr and the pet cock Z, used whenthe invention is applied to a carbonating pump, are omitted. An ironsupply pipe 7c having a screwthreaded extremity, is substituted for saidsupply coupling 7c; an iron discharge pipe l having a screuf'threadedextremity, is substituted for said pet cock Z; an air dome T isconnected with such discharge pipe Z.

that I claim is:

l. In a pump, the combination of a suitable base, pumping mechanismvertically adjustable on one face of said base, such mechanismincludingV a driving shaft and. a gear mounted thereon; and a motortransversely adjustable upon the top of said base and bearing a pinionadapted to mesh with said pump gear.

2. In a pump, the combination of a suitable base, a bracket verticallyadjustable on one face of said. base; pumping mechanism wholly supportedby saidbraeket, suchmechanism including` a driving shaft anda gearmounted on said shaft, and. a motor transversely adjustable on the topof said base, said motor having its armature shaft alined. with saiddriving shaft and provided with a pinion adapted to mesh with said gear.

8. In a pump, the combination of a suitable base, a bracket verticallyadjustable on one face of said base; two valve chambers mounted on saidbracket, said` chambers having their corresponding extremitiesrespectively connected with an inlet and an outlet passage and beingprovided with horizontally extending lateral connections intermediate ofsuch extremities; plunger cylinders having horizontally extendingportions respectively rotativcly secured to said lateral connections,said valve chambers having valve seats respectively to opposite sides ofsaid connections; valves respectively adapted to such valve seats, adriving shaft mounted in said ln'acket, a gear .mounted on said drivingshaft; plungers in said cylinders eccentrically connected with saidshaft so as to be reciprocated thereby; an idle gear mounted on saidbracket and meshing with said driving-gear, and a motor transverselyadjustable on the top of said base, said motor having its armature shaftalined with said driving shaft and provided with a pinion adapted tomesh with said idle gear.
